ALCOHOL-LAM P.

SPECIFIGATION forming part of Letters Patent No. 724,543, dated April 7, 1903.

Application filed August 27, 1902. Serial No. 121,164. (No model.)

To all whom it may concern Be it known that we, J AMEs W. CHAPMAN and MICHAEL SEIPS, citizens of the United States, residing at Meriden, in the county of so that the flame may be varied and controlled at will.

In the drawings, Figure 1 is a side elevation of one form of lamp embodying our invention. Fig. 2 is a vertical section of the same. Fig. 3 is a vertical section similar to that shown in Fig. 2, excepting that it is taken in a plane at right angles thereto. Fig. 4 is a plan view of anotherform of lamp embodying our invention. Fig. 5 is a vertical sectional view of the same. Fig. 6 is a projection ofgthe upper part of the same lamp looking up from the inside.

A is a font or reservoir for the liquid fuel,

. alcohol, or other suitable gas-generating element. B is a suitable cover'therefor.

C C are wick-tubes leading up from the lamp-font to a tube or hollow ring D, in which one or more gas-passages E E are provided. Above the ring D is a gas -space, formed by an annular hood F, in which a series of fine perforations f are arranged for the purpose of permitting the gas to pass out of said gas-space to the flame.

G is a valve for the gas passage E in the ring D.

G is a valve-stem for each valve G, two being shown.

H is a bar connecting the valve G G.

I is a suitable connection between the bar and the crank-pin J of a controller K, the latter being preferably provided with a suitable handle K. Each valve-stem G passes down through the ringD and the tube C. A means is thus provided for operating the valves G G. A wick L leads from the chamber A to the ring D.

to supply the flame.

M is a suitable wick-like filling within the ring D, as best seen in the sectional view, Fig. 3.

The wicks L convey the alcohol or burning fluid up to the wick-like filling M within the ring D. This wick-like filling M holds the alcohol in suspension. From the alcohol within the ring D gas is generated, which in operation flows out through the passage or passages E E when the valves are opened,

thence into the gas-space under the hood F, and out through the small perforationsf. The ring D thus acts as a gas-generating chamber. To start the lamp or stove, heat is applied beneath the ring D until suificient gas is generated to light above the holes f.

In the form of lamp shown in Figs. 1, 2, and 3 a primer or startinglamp is provided. N is a wick adapted to convey alcohol-or the burning fluid to the starting-lamp 0, located underneath the generating-ring. P is a cap for the starting-lamp O. In operation the cap P is removed or turned back and the starting-lamp is lighted. The heat from this lamp raises the temperature of the alcohol within the chamber of the ring D and gas is given 06, which passes up through the passages E in a quantity controllable by the valves G G. The gas may then pass out through the small openings f f in the hood F The quantity of gas passing out from the generating-chamber and into the gas-space underneath the hood F may be varied and controlled by turning the handle K. This turning of the handle K imparts through the connections before referred to a movement to the valves G. Manifestly this is simply one convenient form of mechanical movement, and it should be understood that the same is capable of many variations.

In the first form of lamp shown in Figs. 1, 2, and 3 guides Q Q are provided within the lamp-font to hold the valve-rods G in the proper position. When the gas has been generated by the starting-lamp so that the flame will burn above the hood F, the starting-lamp 0 may be extinguishedfor instance, by placing the cap P over the flame.

If desired, the starting-lamp 0 may constitute a removable stopper as indicated, for example, for the purpose of refilling the lampfont.

Obviously it is not essential to the invention that the starting-lamp 0 be employed. The ring D might be heated by other means. The provision of a starting-lamp insures an ever-ready and convenient means for starting the generation of gas. There is the disadvantage, however, that the operator may neglect to extinguish the primer-flame when the lamp or stove has been started, in which event unnecessary heat is applied to the generator-chamber D. In the form of lamp shown in Figs. 4, 5, and 6 it is intended that it is shall be started by applying a suitable match or taper underneath the ring D, which is quite sufficient for all ordinary cases. In this form of lamp it will be noted that the tubes 0 C have been extended down into the chamber or font A. The extensions 0' C are then slotted on the inner edges to afford gnideways for the ends of the bar H, connecting the valve-rods G G. The crank-pin J is formed integral with the end of the controller-rod K by milling it down. The connecting-rod I is pivoted to the bar II, and thus a simple and efiective means of operation is provided for the valves E E.

The distance of the generatingchamber D from the font A ordinarily prevents the heating of the fluid in the font. Gas is, however, sometimes generated here in small quantities and is sometimes forced back from the generating-chamber D by the sudden closing of the valves E E. We have therefore provided an auxiliary outlet or escape through the tube R, having holes r r at the upper end. This tube R is inserted in the top of the dome-like portion B of the cover B. Any gas passing out in this manner will be lighted at the top by the flame there and will die out as soon as the pressure becomes normal.

It has been found that by these constructions and obvious modifications thereof the size of the flame may be readily varied to suit the desires of the user. \Vhen it is desired to extinguish the flame above the hood F, it is merely necessary to move the valves G G sufficiently to close the gas-passages E E.

In the use of the Word alcohol we intend to include other spirits or liquid fuels that are available in lamps or heaters of this character.
